INNER DISK FOR Application filed .Tune 5,

This invention relates to crushing machines ot the disk action type, and more particularly to the construction and ar rangement of the `inner disk.

lnner disks have heretofore been constructed of tivo or more concentric parts. This practice is adhered to for various reasons, but mainly to provide a certain amount ot flexibility in order to relieve the lo strain on the anchoring element.

rllhe principal objects of my invention are to provide an integral disk construction which will obviate casting diliiculties in that it is capable ot' the necessary expansion and contraction to avoid the setting up (it dangerous or otherwise undesirable strains and stresses, and to provide an integral disk construct-ion having the necessary inherent resiliency to reduce the strain on the anchoring means to a minimum.

An embodiment ot' the invention is illustrated in the annexed drawings, wherein Fig. l is a view ot the outer tace ot the inner disk otl my invention;

Fig. 2 is a section thereot; and

Fig. 3 is a face view ot a modification.

ln the drawings, the numeral 5 represents an inner disk ot solid or integral construction in accordance with my invention. It is ot general dish shape, as usual, to provide :i grinding tace 6 and an outer tace T tor co-operation with the usual disk head, not shown. The tace 7 has grooves 8, as usual, Al'or the reception ot spelter or other filling introduced between the vface and the disk head.

ln ,turther accordance with my invention l form the disk with an integral tlat central anchoring portion 9 having a central bore HIGH BRIDGE, NEW JERSEY, .A COR- DISK CRUSHERS.

ing bolt shown in dotted lines in Eig. 2. In n order to relieve the strain on the anchoring element, the flat portion 9 is afforded the necessary resiliency through the medium ot alternate thick and thin sections established by the provision of radial depressed panels or pockets 1l, Figs. l and 2. The same rcsult may be attained by substituting, for the panels, the slots 12, Fig. 3, thus providmg resilient tongues 13 for engagement with the anchoring element.

rlhc inn-er disk ot my invention is pret erably constructed of commercial or high per cent manganese steel, the integral construction readily lending itself to the special heat treatment essential to that steel.

Having described my invention, I claim:

l. An inner disk for crushing machines ot the disk action type. having a centrally apertured integral flat center with panels ranging radially thereof to provide alternate thick and thin metal sections whereby suiiicient resiliency is established to relieve the strain on the anchoring means.

2. An inner disk for crushing machines of the-disk action type consisting of a unitary casting ot manganese steel dished to provide a central -Hat portion and an oil'set grinding portion, the iat portion having an axial opening to receive an anchoring element, and being radially relieved ot metal `in the region of said opening whereby it is capable or absorbing tlow or stretching of metal in service and so minimize. strain on the anchoring element.
